Hello,

I have a new project that needs to use two servos to automate a puppets head. I have never used servos before so I have been looking at examples online and using a Arduino R3 to prototype. I know the servos are 3v-6v, but is it safe to power two off the a tinyDuino or should I take the approach of using a different power supply?

This is the servo I am using:

The example of using a servo:

It won't hurt the circuit if the servos need more power.

If the servos run out of power your project just won't work, it will act like an RC Car when the batteries go dead. If you see this happen then I would should jest using a wall wart (power supply) to run your project.
